In Haruki Murakami's novel "Norwegian Wood," the quote emphasizes the interconnectedness of human emotions and experiences. When someone is hurt, it often leaves a mark not only on the individual but also on those who care about them. This shared burden of emotional pain highlights the complex relationships we have with one another, where one's suffering resonates with others.

The quote suggests a deep empathy and recognition of our responsibilities in relationships. When we hurt others, we also inflict pain upon ourselves, as the emotional ties between people can create a shared experience of suffering. Murakami captures the essence of love, loss, and the lasting impact our actions have on the lives of others.
